The judge dominated his lifestyles sentence should include a minimum of 30 years in jail.
his victims bravely fought back against him.
The battered and bruised mugshot is from 2017 when Sinaga, 38, was first arrested through Greater Manchester Police.
Images have been released for the primary time ahead of a BBC documentary, Catching a Predator, being aired.
The obsessive rapist attacked more than 200 males, and was once jailed for life closing yr, however he was no longer caught for more than a decade.
His horrific crimes handiest came to light after he was found in a pool of blood on the bathroom ground of his rental on Princess Street in Manchester town centre in June 2017.
Sinaga arrived in Britain in 2007 to review at Manchester University and was ready to stay in upper schooling due to his rich father.
Vile Sinaga was once crushed so badly via a teenager he had lured back to his flat that medical execs thought he had a bleed on the mind.
The rugby participant sufferer managed to escape the valuables, just about town’s Gay Village, and known as the emergency products and services to regard his attacker.
Sinaga was captured on CCTV being stretchered from his hope, slipping in and out of consciousness and used to be rushed to the MRI.
Despite knowing that he had dedicated horrific rapes against hundreds of fellows, Sinaga chillingly requested a nurse when he came to visit if he had been sexually assaulted.
His ultimate victim was the important thing to unmasking the prolific rapist, who targeted lone males and brought them again to his flat prior to drugging them with GBH or GBL.
The rapist posed as a Good Samaritan and pretended to help the teenager in finding his friends, however his victim woke in the middle of the attack.
Unlike the opposite victims, he controlled to fight again – battering Sinaga and fleeing the valuables with the rapist’s phone.
Calling the police, the brave victim said: “Hello, I’ve simply, I used to be out ultimate night time and then some man’s took me to his space that I don’t wish to take me to, wouldn’t let me leave his area, and he ended up trying to rape me.
“I attempted to push him away, I’ve got blood on me because I tried to hit him to get away from me.
I are aware of it’s violent, however I’ve had to hit him a few times just to, to prevent him from attacking me, been on top of me
Sinaga’s Final Victim
“He’s trapped me in his area for lots of the evening.
“I’ve had to, I understand it’s violent, but I’ve needed to hit him a few occasions simply to, to stop him from attacking me, been on best of me.
“I’ve needed to. I’ve were given blood on my hand if you want to see? Cut, I feel he might be busted so, if you have to you will have to telephone an ambulance ‘purpose I’ve, I’ve had to hit him a few times to get him away from me.”
The teenager was arrested on suspicion of inflicting grievous physically hurt with intent, but passed police the key to caching Sinaga, his iPhone.
Sinaga filmed the attacks on two mobile phones, and regularly gave cops the incorrect PIN codes for the units.
But when he ultimately gave up the PIN, he used to be arrested on suspicion of one rely of rape, and used to be handcuffed to his mattress earlier than being discharged and being quizzed by means of police officers two days later.
Twisted Sinaga, known as ‘Rey’ to his friends, stored “trophies” from his victims, comparable to passports and wallets.
‘I LOOK DEAD’
As the sheer magnitude of Sinaga’s offending got here to light, detectives had to determine the boys within the videos, in finding them and give an explanation for that they believed they'd been targeted through the rapist.
One sufferer, Daniel, from Hastings in East Sussex, simplest came upon what had took place to him when the police showed him the footage taken via Sinaga in 2015.
Speaking concerning the attack he stated: “You can see I am comatose. I look useless. It’s horrible to peer.
“I was on a sofa, totally clothed once I aroused from sleep. I may now not have in mind anything.
“Then I saw someone’s toes strolling spherical and I simply iced over. I couldn’t provide an explanation for where I were to my partner.
“I never thought of reporting it to the police. To say as a man I have been raped is a difficult factor.
“It makes you feel so susceptible.”
Because he didn't recall the assault, he had to be tracked down via law enforcement officials to talk to them about the harrowing incident.
That supposed the police had to to find him – and that knock on the door is something he'll never overlook.
Daniel breaks down in tears in the documentary when he remembers the police telling him he’d be raped.
He added: “When the police became up I may just inform from the way in which she checked out me. I knew she knew.
“There used to be no denying it was me. You may just see my tattoo.
“There is just a little of reduction because you understand what has came about finally and you can make sense of it however almost definitely now not the comfort you want.”
‘HIGHLY DANGEROUS, CUNNING & DECEITFUL’
Sinaga was found guilty of 136 rapes and 14 sexual assaults – probably the most offences dedicated by means of one defendant in British criminal history.
The charges relate to 48 identified males and all came about between January 2015 and May 2017.
But police consider that he may well be responsible of assaulting no less than 206 sufferers in his decade-long spree.
Men hardly reported rape assaults so the police didn’t know there was a serial predator in their midst.
Sinaga has been described by way of one detective as a “narcissist and a psychopath”, and was branded “extremely unhealthy, cunning and deceitful” by means of the pass judgement on who jailed him.
He is these days serving a 40-year sentence at HMP Wakefield, known as ‘Monster Mansion’ , and used to be also convicted of eight tried rapes.
In general, a hundred and fifty five men contacted Greater Manchester Police when main points of his crimes become public knowledge back in January 2020.
Of those, 23 had been identified as sufferers via detectives, and all have not long gone forward with a prosecution as they are happy along with his current sentence.
GMP are proceeding to urge anyone who imagine they may had been a victim of Sinaga to come forward.
